The present invention relates to certain new` and useful improvements in radiators, and more especially to that type. employed in .connectionwith water Vcooled internal combustion engines in'fwhich the heate'd water is supplied to an upperjwater chami her, and fiows downwardlythrough'substanti'ally vertic'ally trending waterppassageways to alower water compartment from which'the water issuppliedlto the engine, the Vertical i water passageways being separated by'a 'plurality ofsubstantially transvers'e air passageways through which the Cooling fiuids pass and have contact with the wallsjof the; water p'assageways to reduce the temperatureof the vwater in itsV passage therethrough. This invention is designed to provide a LVradiator of the Vclass described which will efiiciently cool the water in its passage through the vertlcally trending waterrpassageway and has for one of its objects to provide air passageways which are inclined with respect to the horizontal so thatthe current of air passing through Will be deflected with full force against the walls of the vertically trending Vwater passageways forming the air-passageways wherebyjthe efficient cooling thereof is obtained.

My invention has for another of its objects to provide a radiator of the class clescribed in which the air passageways are substantially diamond Shape, whereby a greater area. of the out-erV surface of the water passageway is exposed to the cooling fiuids and whereby the length of such water passageway is considerably increased.

This i Vvention has for a further object to provide means dividing each air passageway and having tapering substantially V- shaped projections on opposite sides to split or divide the air and thus better insure Vits contact with the entire wall area of the air passageways. A i

lVith the above and other objects in view which will appear asV the description pro- `ceeds, my invention vresides inthe novel con- 18.20. seriai No. 888,308.

struction, combination Vand ari'angelnent of 'parts substantially. as hereinafterdescribed and morepart'cularly defined by the 'appended cl-aims, it being unders'tood that such vchanges Vln the precise embodiment ofV the herein disclosed invention may be .made as come within the 'scope o f the claims.

inV the accompanying ,dra-Wing Ighave llustrated one complete example of: thephysical em'hodimentfof my invention constructed according lto the best mode 'If have sofarf' de- `vised for the practijcal application? of the principles ,th'ereof,' and in which; w 7

Figure 3 is a fragmentarysectional view taken on the line 3-3 of'FigiJre 2; and Figure 4 is'a fragmentary sectionali'view taken through the. radiator at 'substantially right angles with respect to Figure 3, on the line-ofFignreZ 'i As is common in radiator constructions employed for use in cooling the water sup-l pliedyto the water jackets ofv internal combustion engines, niy improved radiator comprises an upper water conipartinent, a lower water compartment,vsubstantially vertically trending water passageways connec'ting` the upper and lower Vwater l'cornpartments, and aV I plurality of air passageways between the water passageways for 'cooling the same and Iieducing the temperature of the'waterjas 'it i passes i therethrough. i

In the accompanying'drawing but a porvtion of a radiator is shown, and in such drawing the numeral 5 designates the upperV water compartment, 6 the substantially vertically trending water passageways connecting the upper water compartment 5 and the lower compartment (not shown), and 7 the plurality of air passageways disposed between the water passageways `The present invention relates more particularly to theradiator core members which form the water and air passageways, and consists of 'lengths of flattened tuhing or the like arranged in pairs and provided Vwith a Vplurality of opposed angular bends or corrugations 8' providing the s'ubstantiallyiV diamond Shape air passage`waysif7- As best shown in'Figure 3, the core members of 'each 'pair have Vtheir innermost bends 9 ahntting f and secured together` in any. desired man-T ner, and: the adjacent members of Veach -adjacent vpair-h.ave their outermost angular bends 'in register and securing therebetween inserts 10, to be later described;v r i I The points where the core members abut are slightly fiattened to provide a betterl connection therebetween,` and this assures a rigid construction. The angular corrup'ations or bends in'the core members are inclined downwardiy and forwardly With respect to the horizontai, whereby currents of air entering'at thefront thereof, will be defiected against the portions of the core members foriiiing the bottoin walls of the air passageways and thus iiisure the contact of the Cooling fiuids with) the walls forming the water passageways.V W

In foriner constructioiis eiiiploying the substantially horizonta'l air passageways,

the contact of the Cooling fiuids with the walls forming the air passageways is not positive, and oftentiines will barely contact therewith; 'My construction eliminates this difficulty as the downward inclination ofthe air passageways insures the positive eiigagei ment of the air currents, and ffurtherinore creating a current whereby the air Will be rebounded or defiected to .the upper Walls of the passageways.

An advantage in Shaping the'air passageways as disoiosed inthe drawing` is that the i length of the water passageways is considerably increasedas well as the Cooling area,

and when the corrugations are less pro-t nounced, this advantage is not obtained. o

The inserts 10 form Cooling fins, and at 1 theV same time have. projections 11 struck therefrom, or otherwise forined on opp'osite sides thereof, in line with the air passageways to divide the current-S of air passingi therethrough and insure the morepositive i contact of the air with the entire wall area of the passageways 7.

The projections 11 Vare substantially V- Laeaao? shaped, tapering or diverging rearwardiy to-divide-the air in two, causing part to be defiected to the upper wallV area and ;part to'rthe iowerywal'l area, therentire air 'being deflectedsomewhat to theside. rii`he Vopenings 12,' fornied by the projecti'ons serve to permit the passage of a' portion of the air cur'rents from onejside of the inserts to the other and thus setup veddying currents. o W p o Froni'the'foregoing description taken in connection withV thev acconipanying drawing it will-be at once. appare-nt to th'ose'skilied in the dart to which an'invention of` this character appertainthatl have provided a radiator constructionwhich is efficient and practical for the purpo'se 'de'sor'ibe'd.

What I claim as niy invention is: i l1. A radiator construction coniprising a piurality of core members p'roviding substantially verticaiiy trending v'water passageways, and bent to form siibstaiitiaily horizontai, vupwardiy and: rearwardly inclined air passagewaysfextending .between .3

shaped projections carried by the iopporsite j i sides of' each insert for 'defiecting the air against the walls of the air passagewaysy' n'wtestimony whereof, I afiix my signature. f i
